Also iv been looking and there are a lot of Volt Mods for my Asus p4p800 se is this the answer
Settings were as followed
3.8ghz:
CPU FREQ = 240
DRAM = 400
AGP/PCI = 66/33
CPU CORE = 1.5750V
AGP VDDQV = 1.7V
P/MODE = STANDARD
3.9/4ghz:
CPU FREQ = 245/250
DRAM = 320
AGP/PCI = 66/33
CPU CORE = 1.6V
DDR = AUTO
AGP VDDQV = 1.8V
P / MODE = STANDARD

PC SPECS:
Pentium4 3.20ghz

I think you want too much off your system.
Personally I'd be happy and am happy with a 240 FSB.
I have a 3.2GHZ EO stepping and am running it a 240 FSB without any hiccups!
It's been 18 months for me.
Also your running 1.57v on your CPU? Man That's way too high!
5 FSB is not worth it!
Mine's at 1.435 and that's plenty.
Your AGP voltage I would not touch!
You can run 2.85v on memory. that shouldn't be a problem.

IMO I would get the most stable OC you can get WITHOUT upping too much your CPU voltage.

Good luck

But at Auto my cpu uses 1.5v

you must have a 0.13um cpu. If that's the case than you can up it to 1.65v but you have to check your temps.
Your chip might be maxed out also.
If you have a 90nm chip than 1.55v should be max.

Good luck
